Thomas's floppydrive is currently on my bench : as we were unable to find the rights parts I proceeded to 3D print them.
A sleeve for the existing 60 Hz pulley was made from PLA, a replacement belt was printed using "Ninjaflex".

The resulting combination is already running for several hours, the belt is as flexible as the original and shows no signs of wear yet.

( This particular drive has the distinction of using a true rubber belt, not the reinforced textile band you normally see )

This ninjaflex  material could potentially be very useful in producing capstans....
Experiments will follow as soon as time permits !
